The ULTIMA mono amplifiers are designed for the most advanced high-quality audio systems, which require the power supply of large speakers that are difficult to drive. They provide unparalleled power supply and are capable of driving any speaker effortlessly.

The ULTIMA is the company's most comprehensive amplifier in its 30-year history and is based on three decades of advanced amplifier manufacturing by Chord Electronics. It features an entirely new circuit topology, the first new design since the early days, with new dual power supply error correction technology.

The ULTIMA contains next-generation Chord Electronics amplifier technology, with advanced error correction topology and advanced concepts for ultra-high-frequency power supplies.

The unique ULTIMA amplifier unit features 64 proprietary MOSFET power supplies that require advanced and refined driver circuits without elements that degrade the sound. The driver circuit features a high-voltage, low-distortion amplifier operating at very high speed: 300 volts per microsecond with advanced power supply and feedback compensation techniques.

The ULTIMA is extremely powerful, offering 780 watts at 8 ohms, 1,400 watts at 4 ohms, and 2,500 watts at 2 ohms, with a maximum output current exceeding 500 amps, providing stunning dynamics, dedication, and unique melodiousness.
